Almarg,
The larger cache may be needed to handle the higher res formats that this device is advertised to handle.
I think that would be the main purpose.
I can see this as an effective though pricey out of the box solution for those seeking the bleeding edge of current digital formats.
Personally I will stick to the music server approach but I can understand if many are not comfortable mixing computers with their audio on their own.
